FM is Forever
Personally, whenever I shop for a new phone, having an FM radio is at the top of my must-have feature list. But then I spent a lot of years in the company of Madison's Solid Rock, 94.1 WJJO. So maybe FM only matters to people who have (or had) access to good music through it.
Still, when aliens invade and enslave humanity and radioactive hamsters from a planet near Mars nom on the datacenter cables, I'll still be able to listen in to the rag-tag gang of freedom fighters broadcasting from their mobile ad-hoc pirate radio.
So would activating FM save lives in a hurricane? Some, but probably not many. Would it certainly help people pick up the pieces after a hurricane has torn up the infrastructure and left people with absolutely nothing First World? Definitely.
I'm all for forcing everyone to include FM in phones for all NEW phones. And for companies choosing to push a software update IF their phone is capable. But forcing all existing phones to retroactively turn on the chip when proper connections to the headphone jack, USB port, or a real antenna has not been done? When real physical limitations make the chip useless, well that's just stupid.
